　　The stitch formation technology of spring pins is a complex and precise process that determines the quality and performance of the pins.

　　One of the key aspects is the manufacturing process of the spring - loaded mechanism. High - precision machining techniques are required to produce the plunger, spring, and barrel with accurate dimensions and tolerances. CNC (Computer Numerical Control) machining is commonly used to ensure the precision of each component. The spring, in particular, needs to have consistent spring force and fatigue resistance. Specialized spring - making equipment is used to wind the spring with the correct wire diameter, pitch, and number of coils. Heat treatment of the spring is also crucial to optimize its mechanical properties, such as elasticity and durability.

　　The assembly process of spring pins is another important part of stitch formation technology. Automated assembly machines are often employed to ensure high - speed and accurate assembly. These machines can precisely insert the spring into the barrel and then fit the plunger, ensuring that the components are properly aligned and the overall function of the spring pin is intact. Quality control during the assembly process is strict, with various inspection methods used to detect any defects, such as incorrect component dimensions, misalignment, or insufficient spring force.

　　In addition, surface treatment technology also affects the stitch formation of spring pins. Surface plating, such as gold plating or nickel plating, is commonly used to improve the electrical conductivity, corrosion resistance, and wear resistance of the pins. The plating process needs to be carefully controlled to ensure an even and uniform coating, which is essential for reliable electrical contact and long - term performance.
